Key Air Pollutants

CO

Carbon Monoxide (CO) can be fatal when inhaled in large amount as it reduces the amount of oxygen present in haemoglobin

Particulate Matter 10 (PM10) are tiny particles in the air which are 10 micrometres or less in diameter, and can be drawn deep into lungs while inhaling

PM10

PM2.5

Fine Particulate Matter 2.5 (PM2.5) is an air pollutant that is a concern for people's health when levels in air are high. PM2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated

Sulfur Dioxide (SO2) is a toxic gas which aggravates existing cardiovascular diseases and causes respiratory illnesses and is a major precursor of acid rain

SO2

NO2

O3

Long-term exposure to ground-level Ozone (O3) can reduce lung function. O3 is created by chemical reaction between other harmful gases
